Sources of coal in NTPC - Kusmunda block & Gevra mines.
Resources of coal – By road and by trains. Coal size – 200mm approx.
COAL HANDLING PLANT

a pulverize mill is used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants.
The crushing process of coal after that there size is <20mm.
CRUSHING OF COAL :-

Coal dust is a fine powder of coal. In this process after coal size is 0.6mm.
Pulverization :-

A furnace is a device used for high-temperature heating.
The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces.
Furnace (burning step) :-

A boiler is a closed vessel in which water or other fluid is heated.
Boilers produce steam to be used at saturation temperature.
BOILER :-

A turbine in which a high-velocity jet of steam rotates a bladed disc or drum.
A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft.
STEAM TURBINE:-

How does an Alternator work ? Alternators are the workhorse of the power generation
industry .It is capable to generate AC power at a specified frequency. They are also referred as Synchronous generators. This video gives a detailed and illustrative introduction on working of alternators.
Electricity is produced in alternators by electromagnetic induction. To generate electricity in a coil either the coil should rotate with respect to a magnetic field or a magnetic field should rotate with respect to the coil.
ALTERNATOR:-

A power station, also referred to as a generating station,power plant, powerhouse, or generating plant, is an industrial facility for the generation of electric power. Mostpower stations contain one or more generators, a rotating machine that converts mechanical power into electricalpower.
GENERATOR:-

The giant, jug-shaped cooling towers you see at old power plants make the turbine more efficient. Boiling hot water from the steam turbine is cooled in a heat exchanger called a condenser.
COOLING TOWER:-
![Page 14: vocational training presentation on korba ntpc](https://reader033.fdocuments.us/reader033/viewer/2022061417/5875b3e31a28ab8b618b6a8b/html5/thumbnails/14.jpg)

The electricity travels out of the generator to a transformer nearby.
ELECTRICITY CABLE:-

Electricity loses some of its energy as it travels down wire cables, but high-voltage electricity loses less energy than low-voltage electricity. So the electricity generated in the plant is stepped-up (boosted) to a very high voltage as it leaves the power plant.
STEP-UP TRANSFORMER:-

When the Coal combustion takes place in the boiler, some part of the coal remains unburnt and that un-burnt particles are called the ash.
ASH HANDLING PLANT :-

SAFTEY
Use of helmet Do not touch any equipment without permission Use of shoe when going to inside of plant

Economical for low initial cost other than any generating plant.
Land required less than hydro power plant . Since coal is main fuel and its cost is quite cheap
than petrol/diesel so generation cost is economical. There are easier maintenance. Thermal power plant can be installed in any
location where transportation & bulk of water are available.
Advantages:

19
The running cost for a thermal power station is comparatively high due to fuel , maintenance etc.
Large amount of smoke causes air pollution. The thermal power station is responsible for Global warming.
The heated water that comes from thermal power plant has an adverse effect on the lives in the water and disturbs the ecology.
Overall efficiency of thermal power plant is low like less 30%.
